O: Spring in the Arroyo

O: Spring in the Arroyo: Approximately10 mile round trip walk from Casting Pond in Pasadena's Lower Arroyo to Hahamongna Watershed Park near JPL and return. While this walk could be considered 'easy' because it is mostly along flat walkways and trails it could also be considered 'moderate' since it is 10 miles. The hike will cover a variety of geographic features, including stoney paths, soft sand along the stream (which may require getting your feet wet when crossing), wide manicured trails, one hill climbing up to the dam, and beautiful tree-arched paths along the golf course. Dogs not allowed. Meet at Lower Arroyo Park /Pasadena Casting Pond parking lot (415 S. Arroyo Blvd; Pasadena 91105). Google link to this address is: https://goo.gl/maps/a3AvtJqHKdf3qf3cA . Take California Blvd W of Orange Grove Blvd to Arroyo Ave, turn N 1 block, turn W down into Arroyo. This is a Front country outing.
